6. How good was this quiz?
- wait, is that a squirrel?
- meh
- simply fabulous
- it was very good, thank you for asking
7. The products of the photolysis (splitting) of water are...
- O2, H+ and an electron
- H+ and an electron
- OH-, H+
- O2, H+ and a neutron
8. What is the function of light in the light-depedent reaction?
- photolysis of water, to reduce glycerate-3-phospate, to make ATP
- To make ATP, photolysis of water, to excite an electron in chlorophyll
- To reduce CO2, to make ATP, to excite an electron in chlorophyll
- To make ATP, photolysis of water, To enable the chlorophyll to take up an electron
9. As the electron moves down the electron transfer chain in the light-dependent reaction it...
- loses energy
- gains energy
10. In the calvin cycle, some of the Triose Phospate created is converted into glucose. What is NOT a possible use of the glucose produced?
- Conversion into starch for storage
- Making proteins
- Nitrification in roots
- Use in respiration
11. Why is hot methanol used to drop samples of photosynthesising algae into in the Calvin lollipop experiment?
- Because it is a limiting factor to photosynthesis
- Because it instantly stops the reaction by denaturing enzymes for photosyntheis
- Because it instantly stops the reaction by boiling the water present in the algae
- because it allows substances into which C14 is incorporated to be identified
12. Where does the light-independent reaction take place?
- In the stomata
- In the stroma
- In the chloroplast membrane
- In the thylakoid membrane of the chloroplast
13. What two products from the light-dependent reaction are used in the light-indepedent reaction?
- ATP and NADPH
- O2 and ATP
- O2 and NADPH
- NADPH and H2O
14. Why is the rate of photosynthesis not equal to the net uptake of CO2 by a plant?
- Because some CO2 produced in respiration is used for photosynthesis
- Because venus flytraps are carnivores
- Because the rate of photosynthesis increases with temperature
- Because CO2 is used only in the light-indepedent reaction
15. 'The rate of photosynthesis is affected by the factor whose level is at the least favourable value' this is called the...
- least favourable factor
- limiting factor
- stopping factor
- limited factor
